' PHOTOGRAPHY.

To all whom it may concern:

Be it known that I, CHARLOTTE E. C.

KINNEY, of New York, in the county of New York and State of New York, have invented 5 certain new and .useful Im rovements in Photograph and I do here y declare the following to e a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain useful im provements in photography.

With the apparatus and means now in use for photographing the size of the image of.

the object hotographed is subject to the limitation 0 the capacity of the photographic lens used. 7

My object is to roduce, in connection with a photographic ens, magnification of the image of the object being photographed and photographing said image by thephotographic lens.

My invention consists, broadly, in using with any camera and its lens a magnifying 2 5 device or lens interposed between the object to be photographed and the plateas a means for producing and photographing an image of the object to be photographed enlarged beond that produced by the photographic 3'0 ens. I carry out this object by interposing between the object to be photographed and the camera-plate an enlarger or magnifier to produce, an enlargement or magnification of the image of the object to be photographed. 3 5 This enlarger or magnifier should be adjustable so as to produce at will different degrees of magnification of the image. Preferably I use an adjustable enlarging-lens and interposethat lens between the photo graphic lens and the object. 1

lwill now describe. an embodiment of my invention, illustrated in the accompanying drawings, and then point out the invention in the claims.

Fig. 5 shows a modification. Fig. 6, is a detail sectional view. Fig. 7 is an enlarged view of my improved apparatus in operative position with i camera, the latterbelng indicated in dotted mes.

Referring to the drawings, A designates a Specification of Letters Patent. Application filed May 27, 1897. Serial No. 633,418-

base adapted to rest upon a table or the like, the same being provided at one end with a vertical member a, provided with longitudi nal slots a, in which fit threaded studs 11 extending rearwardly from rightangular 6o strips a between which the object is secured. Said strips are held in .position by bindingnuts a, working on the threaded portions of studs (1- and binding against the edges of slots a. The strips a extend entirely across the board a, and by rendering them adjustable with relation to each other the objectsay a picture of any size or dimensions-may be readily secured in position.

The base A is provided with a central lon- 7o gitudina'l cut-out b, the longitudinal edges b of which are grooved at b to receive correspondingly-reduced portions b formed in t e longitudinal edges 6' of a member B. Said latter member is also cut out at d and provided with grooves or guideways d, adapted to receive the reduced edges d of a second sliding member D. To the member D is secured a vertical tubular standard 2, adapted to receive a rod 0, which is adjustable longi- 8o tudinally therein, the same bein retained in its adjusted position by means 0 a set-screw e The upper ende of said rod is threaded and adapted to engage a conical casing E, which is open at its rear end 1 a lens 3 being secured in the forward end thereof. The size of this lens and casing may be varied at will, according to the size it is desired to make the enlar ement of the image of the object photograp ed. The casing may be en- 0 tirely dispensed with and the lens secured in an ordinary rim 6, as illustrated in Fig. 5.

If the apparatus'be used to photograph a photograph or print in practice, the photograph or print is first secured between the 5 strips a of the upright a and the hei ht of the lens a adjusted to correspond t erewith. The sliding members of base A are then adjusted until the desired focus is obtained, it fre uently bein necessary to move said lens wit 1in two or t rec inches of the object, the distance varying according to the character of the lens employed. The camera to be employod, which may be of any size, form, or make, is then placed in such position as to hotograph the image'now seen magnified: n this manner the image of the object is magnified by the lens 6 before reaching the camera-lens and the magnified image thus obtained is photographed. Prints may be 11- 1s. he will be seecielly 0b- 7 V. enlargement of 952 1 3 image of e 0e photographed may be made image photographed in any lightby which an er= ed only t may be W xpleyed i011.
